Domestic US Visa Renewal Case Details and Discussion

I went through the Canada process, which does not have an appointment date system. 29 Jan: Submitted application, paid fees. 29 Jan: Mailed the documents via USPS label provided. 31 Jan: Documents delivered by USPS. 31 Jan: Email confirmation from [email protected] (The GDIT Visa Appointment and Information Service Team) that documents were received. 14 Feb: Email confirmation of “documents released” with USPS tracking number. No information about whether Visa was approved. 16 Feb: USPS tracking actually received the package. 20 Feb: USPS delivered package – signature required. The flat rate envelope had my passport, a note on a small sheet saying general legal stuff, and the photograph I had sent (I guess they just scanned it and returned it back). Passport had the approved visa stamped. CEAC website never showed any status for my application. Always “Your search did not return any data”.
